The legalization of recreational marijuana is only days away in Canada. This grand experiment will draw the attention of the world. While legalization may seem like a small innovation amongst the monumental scale of world history, its effects will, in fact, be sweeping.

Marijuana legalization will be transformative. With this step, Canada is poised to change the world and its standing within it. Here’s how:

During a debate this week between Texas gubernatorial candidates Republican Governor Greg Abbott and Democratic Sheriff Lupe Valdez, the subject of marijuana came up. The question was asked, “What is your stance on marijuana legalization in Texas?”

Marijuana stocks ripped higher Thursday after the U.S. Drug Enforcement Administration classified a cannabidiol-based drug made by GW Pharmaceuticals in its least restrictive category, setting the stage for commercial launch.

Think of the states as dominoes lined up one by one. When the first domino topples, it leads to a chain reaction that causes most, if not all, of the others to fall. That’s what has happened, and continues to happen, with state legalization of marijuana. The timeline for marijuana legalization in the U.S. shows how those dominoes keep falling.
